Hi everyone,

i'm new to sharpMap. I try to combine multipe vector-layers (lines, polygons ...). Is there any chance to get the fill-Property of  Layer.Style semitransparent?

Or is a different solution out there to visualize my vector-stuff semitransparent (over a raster-image)?
My only idea is to create multiple map-instances and to merge that output with rasteroperations to a new Image.

Thanks for your help

Hi ksk_tom, you need to set the alpha part of the StyleColor
 eg: layer.Style.Fill = new StyleBrush(StyleColor.FromBgra(red, green, blue, alpha))

where alpha is an int between 0 and 255 (0 is totally transparent, 255 is totally opaque) hth jd
